Did You Know #DYK: How To Extinguish Different Kinds of Fire?

by Roxanne Mustard | posted in: Did You Know | 2

How To Extinguish Different Kinds of Fire?

Did you know that in order for a fire to exist there must be four elements present? The four elements are namely oxygen to sustain combustion heat to raise the material to the correct temperature, fuel to support combustion and a chemical reaction – (Oxygen + Heat + Fuel) = Chemical reaction. This very simple formula will determine the extinguishing agent you need to be using in order to put out your fire.

How many people just run for water when there is a fire?

Unfortunately, it is not that simple!

Let me simplify the concept of fire and how we can extinguish these fires:

Types of fire:

Class A – Ordinary combustion, these are flammable materials and these fuels the source e.g. Wood, cloth, paper and even your basic day to day trash.

Class B – This fire source uses flammable liquids e.g. petroleum, different kind of tars, oils and even paint.

Class C – Energized electrical equipment/components e.g. Computers, servers, motors, transformers and our daily appliances.

Class D – Combustible metals e.g. magnesium, titanium, sodium, lithium and potassium – these are mainly present in a laboratory environment.

Class K – Cooking oils and greases – We all cook meals with either vegetable or animal fats and these are the components that can start this fire.

Now that we know about and understand the different classes of fire, let’s discuss our different options for extinguishing these fires.

The different types of fire extinguishers:

Water – The water extinguisher has a cooling effect on the burning agent causing the fire to burn more slowly.

Powder – Dry powder extinguishers smother the fire and form a barrier between the fuel and the oxygen that is allowing the fire to ignite.

Foam – Foam extinguishers have a cooling effect on the burning agent, creating a barrier between the flame and the fuel that is causing the reaction.

Carbon dioxide – CO2 Extinguishers suffocates the fire allowing it to kill off the oxygen that is reacting with our fuel source.

Wet Chemical – Wet Chemical extinguishers work by creating a layer of foam that prevents the oxygen from fuelling the fire. It creates a cooling effect and kills the fire.

The last thing we will be discussing to solve all your fiery situations are which fire extinguisher types to use for the different classes of fire:

Type	Class A	Class B	Class C	Class D	Class K
	Combustible Materials	Flammable Liquids	Electrical Equipment	Combustible Metals	Cooking Oil & Gas

L2B Blog: History of Hard Hats

by Sasha Anderson | posted in: Construction Chat, Construction Events, Did You Know, General, Safety | 0

.History of Hard Hats

Hard Hats; a common symbol of the Construction Industry, but have you ever stopped to wonder about the History behind this safety accessory?

History

According to Prescot Valley Tribune, “The Hard Hat originated with Edward Bullard, a WWI veteran. He brought a steel helmet home after the war. This metal headgear was the inspiration to revolutionize industrial safety. Bullard’s father worked in the industrial safety business for 20 years and sold protective hats, but they were made of leather.

Construction of the Hoover Dam, which began in 1931 was the first project in which construction workers were required to wear Hard Hats. Later, in 1933, the construction site of the Golden Gate Bridge became America’s first “Hard Hat Area”.”

The first Hard Hats were made from:

Leather
Canvas
Steel
Aluminum
Fibreglass
Plastic
and finally today’s High-Density Polyethylene (HDPE).

Functionality

The function of the Hard Hat is pretty obvious. If worn and fitted correctly it provides limited safety from shock, perforation, fire, water and heat.

Hard Hats also provide a form of identification.

A wearer can use colour coded Hard Hats to differentiate between job titles/responsibilities:

White – Managers, Engineers, Supervisors/Foremen
Blue – Electricians, Carpenters and other technical operators (besides civil workers)
Green – Safety Officers
Red – Fire Fighters
Yellow – Labourers
Brown – Welders and workers with high heat application
Grey – Site Visitors

These colour codes are general and could change according to the Project.

Over time Hard Hats, like most things also need replacing. As a wearer, you should inspect your Hard Hats before each use. Your support strap should also be replaced annually and the entire hat every five years. Hard Hats may also allow for the attachment of safety accessories; most noteworthy are face shields, respirators, hearing protection and work lamps.

Future

Today’s Hard Hat hasn’t changed much since the 1960’s and has become a staple of safety, but they may be getting an upgrade in the future.

According to Sourceable, “In Australia, RMIT has developed a system whereby sensors can be embedded onto safety glasses, helmets or boots and can monitor and inform workers of impending danger…”
Sounds really interesting, after all, technology is a part of our every day lives and why not safety too.
Industry leaders can achieve much by ‘upgrading’ the Hard Hat. For example, by monitoring and assessing stats you can take precautions; not only in the present but also in the future through behavior analysis. But this may also present issues; like how much monitoring is too much when it comes to privacy and tracking? What are your thoughts?

In conclusion, the future sure looks safe when it comes to Hard Hats. The History of Hard Hats was certainly an interesting topic to research and blog.

Finally

Do you have any Hard Hat stories or facts you’d like to share? Or do you frequently use one?
